Short for Resilient Hyaluronic Acid, RHA is the only FDA approved hyaluronic acid filler for dynamic wrinkles and folds.

Dynamic wrinkles and folds appear in areas of the face that move repetitively. Your face is dynamic, making millions of movements every day. Movements like squinting, frowning, laughing, and talking create dynamic wrinkles and folds. These wrinkles and folds can be difficult to treat because dermal fillers may cause the area to appear stiff or unnatural when the face moves.
